The Gas Clip Technologies MGC-S-PLUS Multi Gas Clip Simple Plus is a portable 4-gas detector that continuously monitors hydrogen sulfide, carbon monoxide, oxygen and combustible gases for three years. Its low-power infrared LEL sensor eliminates charging and routine calibration while remaining immune to common H2S and silicone sensor poisons. A one-button interface, large LCD, audible, visual and vibrating alarms, continuous one-second data logging and IP68 protection support straightforward use in industrial and confined-space applications. The detector is compatible with the MGC Simple Dock for bump testing, calibration and record management.
